Selecting
a
directory
or variable
Your current directory—also known as your path—is showir at the start of
the second line of the status area. To work with another directoiy, you
need to select that directory. You must do this, for example, if you want to
use a variable stored in that directory.
The methods described below for selecting a directoiy are the
same methods you use to select a variable within a directoiy.

Method 1
Use this method if the directory you want to select is below—but not too
far below—the current directory in the directory tree.
1. Press (V№).
A menu of the variables and
subdirectories in the current directory
is displayed. Subdirectories can be
distinguished from variables by a small
bar across the top left-hand comer of
the menu item. The example at the right shows that the HOME
directory contains a subdirectory called ENGIN and a number of
variables: REALA, MODUL, OHM, and so on.
Whenever you press @R), the variables and subdirectories displayed
are just those contained in tire directory whose name is shown in the
status area. Also, whenever you create a new variable or subdirectory,
that variable or subdirectory is placed in the directory whose name is
shown in the status area.
2. Select a directoiy by pressing the corresponding fimction key and then
pressing (ENTER).
In the above example, you press
JD
and (ENTER) to select the ENGIN
subdirectory.
If there are more than 6 variables and subdirectories in your current
directory, you may need to press (NXT) before the name of the
subdirectoiy you want to select appears on the screen.
The variables and directories now shown on the menu are those
contained in the subdirectory you chose. If the subdirectory you want to
finally work with is further down the directory tree, you will need to
repeat step 2 until its name is displayed on tire menu.
